Web service can’t be reached in mendix

Hello everybody !! If we trace the web service log and take the request as it from the server ( mendix console server )  , then try to use the same request on soap on the same server for the same end point it works successfully , but inside mendix it gives the below error  web service can’t be reached , null pointer Java  is there anyway to know the reason behind this problem and make a better investigation ?

Do you have a firewall running or IP restrictions on the web service? It could be the server Mendix is running on doesn’t have permission to access the remote service.
